How does the Earth and Moon look from Mars? Well, to answer this question, NASA has shared a picture of Earth and Moon captured by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. The NASA photo has been shared on its official Twitter handle and is a throwback picture as it was originally taken on October 3, 2007. Sharing the post NASA tweeted, "Mars Reconnaissance Orbiter caught this glimpse of Earth and the Moon. Each of our seven robots now working at Mars is really a #NASAEarthling, acting as our eyes as they explore the Red Planet – deepening our understanding of and appreciation for our blue one."

In the NASA photo we can see that the Earth is covered by clouds while not much detailing can be seen on the moon. "On the Earth image we can make out the west coast outline of South America at lower right, although the clouds are the dominant features. These clouds are so bright, compared with the moon, that they are saturated in the HiRISE images," NASA said. it further added that the moon image is unsaturated but brightened relative to Earth for this composite. The lunar images are useful for calibration of the camera.

As per the information provided by NASA Mars, at the time the image was taken, Earth was 142 million kilometers (88 million miles) from Mars, giving the HiRISE image a scale of 142 kilometers (88 miles) per pixel, an Earth diameter of about 90 pixels and a moon diameter
